Now multiple sources connected to the couple tell TMZ ... over the weekend Victor and Johnny agreed to reconcile and Johnny plans to move back into the family homestead today. He was in L.A. shooting a show over the weekend.

Now the strings ... we're told Victor wants Johnny to sign a document agreeing to publicly apologize for all the nasty things he said about Victor. Johnny must also agree in writing that he will no longer let his mother meddle in the marriage ... and she has to keep her nose out of their finances.

We're told they were squabbling Sunday over the document ... what a shock.
